Prain shook his head with a doubtful smile. "While Arthur Ferris lives Miss Wedderburn won't marry you," he said positively.

Alder stopped at the door and looked back. "See here, Mr. Prain," he remarked earnestly, "I'm all fair, square, and above-board. Gebb here will tell you that before you came I defended Ferris, because I consider him innocent. But I believe that his father killed Kirkstone and my cousin, and I am certain that both crimes will be brought home to him. In that case I have my doubts as to whether a proud girl like Edith will marry the son of a murderer. If she does not, she will accept me, of that I am certain; and I shall do everything to bring such a marriage about."

"Well," said Prain, "I've known Edith all her life, and I don't think she will marry you."

"We'll see about that," rejoined Alder, confidently, and swung out of the door with a look of determination in his blue eyes.

Prain shook his head and shrugged his shoulders, for he thought that the barrister was over-confident for a lover. Then he took up his hat to go, and addressed a last question to Gebb.

"Well, sir," said he, grimly, "and what do you intend to do now?"

"Three things, Mr. Prain, and I don't mind telling you what they are. I intend to question both Ferris and Miss Wedderburn, I intend to search Kirkstone Hall for that confession of Miss Gilmar's, which I really believe exists, and I intend to call upon Mr. Clement Basson."

"What about Basson--can he prove anything?"

"He can prove an alibi in favour of Ferris," said Gebb; and forthwith related to Prain all that he had been told by Alder regarding the lecture in the Grangebury Town Hall.

Prain listened attentively, and nodded his head approvingly, for he was pleased to find a loophole for Arthur's escape.
